Coco Gauff gave the home crowd a reason to celebrate at the US Open, moving on to the fourth round while her fellow Americans Taylor Fritz, Amanda Anisimova and Madison Keys suffered unexpected defeats. The 2023 US Open champion, now 22, faced world No.

40 Cristina Bucsa. Although she was not playing at her peak, Gauff managed to grind out a 6-3, 6-4 victory, securing her place among the last 16 competitors.

Her next challenge will be a quarter‑final showdown with fellow American Iva Jovic. Speaking after the match, Gauff reflected on the differences between day and night sessions: "Playing in daylight feels completely different from under the lights. When I fell behind early in the second set, I reminded myself to speed up my shots and take control." She added, "Bucsa is a crafty opponent who can vary the pace and disrupt rhythm, so it was a battle to find my groove. I’m pleased with how I fought through, even when I wasn’t at my best." While Gauff’s win was a bright spot, the American contingent experienced a rough day.

Taylor Fritz, seeded ninth, seemed poised for a smooth passage to the fourth round after taking a two‑set lead over Argentina’s Federico Cerundolo. The 28‑year‑old, who was runner‑up two years ago, had not dropped a set all week and appeared on track to join compatriots Ben Shelton, Frances Tiafoe, Tommy Paul and Alex Michelsen in the round of 16. However, Cerundolo, fresh off a surprise victory at Queen’s Club earlier in the summer, clawed back into the match, turning it into a five‑set thriller and ultimately prevailing 3-6, 4-6, 6-3, 6-4, 6-4.

The United States is still hunting for its first men’s singles champion since Andy Roddick’s 2003 triumph over Juan Carlos Ferrero. Meanwhile, 20th seed Tommy Paul is set to face world No.

2 Carlos Alcaraz in what promises to be a genuine test of the defending champion’s credentials after his recent injury layoff. Paul remarked, "I think I’ve played Carlos more than anyone on tour, which is crazy. He and Jannik Sinner are the real tests now.

We’ve had some good matches, and even though we haven’t seen much of him recently, he’s looking sharp coming back." Top seed Alexander Zverev also cruised into the fourth round, dispatching Alejandro Tabilo in straight sets, 6-2, 7-6, 6-2. The German star now prepares for a clash with 25th seed Luciano Darderi, who earned his first appearance in a US Open fourth round by beating Australian wild‑card Dane Sweeny 6-4, 6-3, 6-3. Fourteenth seed Learner Tien survived a grueling five‑set battle against Jakub Mensik, winning 6-3, 1-6, 6-7, 6-3, 6-4.

The match stretched into the early hours of Sunday morning, concluding around 1:30 a.m. in New York.

At 20, Tien became the youngest American to reach the US Open fourth round since Andy Roddick’s record‑setting run in 2002, matching that historic achievement. In another upset, Belgium’s 28th seed Alexander Blockx defeated Italy’s fifth seed Flavio Cobolli 6-7(4-7), 6-3, 6-0, 6-3, earning a place in the round of 16 where he will meet Argentina’s 24th‑seeded Cerundolo.

Madison Keys, the 2017 runner‑up, left the court dejected after surrendering a sizable lead to China’s Qinwen Zheng, falling 1-6, 7-6(7-3), 7-5. Keys admitted, "I started strong, but then I got scared and couldn’t swing. Tennis feels really hard right now, and that fear took over." Amanda Anisimova, last year’s finalist, committed 46 unforced errors in a 6-2, 7-5 loss to Austria’s Anastasia Potapova, ending her campaign earlier than expected. Elsewhere, French Open champion Mirra Andreeva beat Czech Nikola Bartunkova 6-2, 7-6(7-5) to reach her first US Open fourth round, where she will face Potapova again.

Six‑time Grand Slam winner Iga Swiatek also dug deep, edging Czech 25th seed Marie Bouzkova 7-6(7-3), 7-6(7-3) to advance. Swiatek noted, "The match was very physical with long rallies. It wasn’t easy, but I managed to stay focused." In the doubles arena, the Williams sisters avoided a fine for not speaking to the media after their loss.

Serena and Venus were defeated in three tight sets by Maya Joint and Chan Hao‑ching in their first match at Flushing Meadows in four years. While players are typically penalized for skipping media obligations, officials have indicated that the Williams sisters will not be punished this time. The US Open continues to be broadcast live on Sky Sports from August 30, with streaming options available on NOW and the Sky Sports app.
